To all whom it may concern:

a of the following description.

Be'it known that I, J Arms T. LrrfiLn, a

citizen of the United vStates, andresiding at Missoula, in the county of Missoula and State or Montana, ,(whose post-ofiiceaddress is 321 East Front street, Missoula, Montana) I have invented new and useful Improvements specification.

provide a device of the above mentioned character, adapted to be secured to a door,

and having an element to engage with the floor, for holding the door open at desired positions, suchdevice beingof simple construction and easy to operate. 1

Other ob ects and advantages of the1n vention will be apparent during the course- In the accompanying drawings, forming a part ofthis specification, and in which like numerals 'areemployed to designate like parts throughout the same,

Figure 1 is a side elevation of the device, with one side of the casing removed,

In the drawings, wherein fol-the purpose of illustration is shown a preferred embodi-,

ment of my invention, the numerallO designates a preferably flat caslng, one s1de of which may be provided with a removable cover, as is customary in the construction of locks. s I V r v The casing 10 1s prov1ded with a gulde bracket 11, rigidly secured thereto and ar ranged therein,and this guide bracket has an opening which is preferably circular Fig. 6 is a longitudinal sectional view elevation of c a but Specification of Letters l atenth 'Patented .9, 1920. Application file d we, 1919. Seria1"No. 3 09,55 8 i for receiving a reciprocatory' stop rod or ele ment 12. This rod extends throughakeyhole opening 13 formed in the lower end 14:

ofthecasing 10. Therod 1'2'is provided at its lower end with a shoe 15, preferably formed of rubber, and adapted to contact 1 i with the floor. The rod.12 is provided with in Door-Stops, of which the following is a a transverse pin 16 arranged within the can r i g i I ing 10, and preventing the rod 12 from mov- My invention relates toimprovelne'nts in door-stops. v 1 V j An'important objectof the invention is to;

ing downwardly beyond a certain di'stan'ce, until the rod is turned upon its longitudinal axis, at 'a'rightangle to its normal position, at which time the pin 16 will pass through the keyhole opening and the rod12 may be removed from thecasing 10. As shown in 1,' the rod 12 carries a washer 17,. en-

surrounding the rod 12 and engagingthe gaging above thepin 16, and this washer engages a compressible coiled spring 18,-

ing by screws 20. This face plate is pro}- vided with a longitudinal recess 21, leading into a longitudinal slot 22. Mountedto reciprocate within the, recess 22 is an operat j ing lug or element 23, having areduced I shank 24, operating within the slot 22. This -Fig. 3 is a: perspective view of the'operat reduced shank is rigidly secured to ajslide.

25, arranged upon the inner side of the face plate .19; To the upper end of this slide is secured a h0using26 provided in its back'f with a longitudinal slot27, andan'opening 28,'in its'front."

' The numeral 29"designates an operating bell-crank lever, pivoted within the casing 10, as shown at'30. The free end of'this bell-crank lever extends into as'lot 31, formed in the rod 12, and is thereby connected with the ,rod and also prevents its rotation. This free end is provided with a lower curved or tapered face 32, which permits the inner arm of the operating leverto be swung viously it may be formed in one piece. The

head 34 operates within the housing 26,-

locked inthe' upper position.

and when the lug 23 is depressed sufiiciently,

the tooth 35 moves within the notch 36,

thereby locking the rod 12 in the upper position out of contact with the floor. To re:

lease the latch-head 3%, a releasing element 37 is arranged within the recess or notch 36,

whi'ch is T-shaped, and this element; is moved inwardly by a button 39, pro ect1ng "to the exteriorof the face plate.

7 To apply the device to a door 41.0, a recess 41 is formed therein through its outer edge, and the jcaslng 10 may then'be inserted within this recess, the rod 12 being disconnected therefrom. QThIs casing is held 1n ,place by screws or the like passing through openings a2 formed, in the face plate 19. A verticalopening i3, is also provided for the rod 12. The face plate 19, however, isnow removed by unscrewing the screws 20, the latch-head an passing through; the lower open end '01 the housing 26. The rod 12 is now passed through the opening {13 and 111130 the casing 10 anl' thrqnigh the spring 18, the rod beingsubsequentl'y turned at a right angle so that the pirrl'G will prevent its displacement. The inner arm of; the bell-crank lever 29 having been swung downwardly, its free end will enter the slot 81 byswinging it up-. 7 w a rdly. The face plate 9 is now brought 30 in proximity to the head 34 and this latchhead passedtherein subsequently to which "the face plate is'secured tothe casing 10. An outer face plate M fits'within a recess 4L 5,jand is held in place by screws l6h This faceplate has openings 1-7 and 28 for the reception of the button 39 and the lug.

hen the button 39 isfpu'shed inwardly,-

the latch-head 31- is released, and the spring 18 projectsthe rod 12 downwardly, so that the shoe 15. engages the floor. 7 By moving the lug 23 downwardly, the bellcranl. lever will elevate therod'12 J and when the tooth Y 35 enters the 'notc h36the rod .will be again .If desired, the shoe 15 may and ametal plate a9secured to the floor, in a suitable position. This plate may be pro- .vided with recesses or notches for the reception ofthe lower endof the rod. This construction is, used when the device; is ap-f plied to a heavy door.

V It is to be understood that the form ofmy invention herewith shown and described is to betaken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without cleparting from the spirit ;of,n1y invention, or vthe scope of the subjoine' d claims.
